stubdom: Add autoconf

Stub domains now use autoconf to build.
This configure script can enable or disable specific domains
and also specify custom download locations for stubdom library
packages. See ./configure --help for details.

C and Caml are disabled by default. vtpm-stubdom is conditional
on the presense of cmake.

Rename vtpmmgrdom to vtpmmgr-stubdom

Also update .*ignore
